The 3.13 / 3.14 / modern-stack changes every other tutorial still hasn't caught up to
15 lessons across 3 modules on genuinely-new-since-2024 Python: PEP 703 free-threaded / no-GIL, PEP 750 t-strings, asyncio.TaskGroup + timeout (3.11+), TypeIs + ReadOnly TypedDict (3.13), pattern matching mastery. Then the modern stack: uv-native workflows (no venv activate), Ruff + ty as your one lint+type toolchain, Pydantic v2 patterns, Polars vs Pandas decision matrix, FastAPI 0.110+ DI. Finally: Anthropic + OpenAI tool-use loops, minimal RAG with pgvector, Playwright async, modern httpx client patterns. Every lesson is under 10 minutes and targets a specific high-intent Google query that every 2022-era tutorial misses.
